Slide bracket for a movable half window screen



April 5, 1938- J. ALEXANDER SLIDE BRACKET FOR A MOVABLE HALF WINDOW SCREEN Filed Dec. 9, 195a JULE ALEMNOER INVENTOR 7 BY ATV RN Patented Apr. 5, 1938 UNITED STATES PATENT OFFICE SLIDE BRACKET FOR A MOVABLE HALF WINDOW SCREEN The invention herein disclosed relates to the mounting of sliding half window screens.

Particular objects of the invention are to provide a simple and inexpensive form of construc- 5 tion by which a screen for the lower half of a window may be slidingly mounted on the outer sash guides of a window frame, entirely from the inside of the window, in such a way that it will not interfere with the free operation of the outl er sliding sash and so that it can not be unin tentionally released from its properly guided relation.

Additional objects and the various novel features of construction, combinations and rela- .5 tions of parts by which all objects of the invention are attained are set forth and will appear in the course of the following specification.

The drawing accompanying andforming part of the specification illustrates one practical em-.

: bodiment of the invention. The structure however may be modified and changed to meet different requirements, all within the true intent and broad scope of the invention as hereinafter defined and claimed.

Fig. 1 is a broken perspective view illustrating the attachment of the upper left hand. bracket to the outer sash guide of a window frame.

Fig. 2 is a similar view showing the right hand upper bracket attached to the sash rail and the 0 screen as being dropped down into position there- Fig. 3 is a broken perspective view illustrating application of the lower left hand bracket to the lower portion of the screen.

Fig. 4 is a similar view showing the right hand bracket applied to the lower portion of the screen, in sliding engagement over the right hand sash guide.

Fig. 5 is a view showing the screen as mounted 0 from the inside of the window and slidingly held on the outer sashguides.

In Figs. 1 and 2, upper brackets are shown at A, A, having channels. defined by side flanges I, 2, connected by back portions 3. Countersunk 5 openings 4, provided in such back portions enable these brackets to be secured by flat-.head wood screws or the like, to the outer sash guide rails I0, of a window frame, with the channels faced inwardly toward each other.

3 After, mounting this pair of upper brackets, a screen, indicated at H, may be lowered down through the channels in the manner indicated in Fig. 2.

Figs. 3 and 4 show the two lower brackets B, B

5 having outwardly faced side flanges 5, connected by back portions 6, and inwardly turned side flanges I, connected by back portions 8, forming continuations of the back portions 6. As indicated in Fig. 3, these brackets are positioned with the outwardly facing channels defined by flanges 5 5, and back portions 6, slidingly engaged over the guide rails or stops l0, and with the inwardly facing channels defined by flanges l, and back, portions 8, engaged over the side rails of the screen. The flanges l at the inside of the screen are shown as having countersunk openings 9, to receive flat head Wood screws or similar fastenings for securing these brackets to the screen.

Fig. 4 shows the right hand bracket thus secured to the screen and slidingly engaged over the sash guide.

The attachment of the top brackets to the sash guides, the lowering of the screen into these brackets and the engagement of the lower brackets over the sash guides and attachment to the screen are all readily effected, at the inside of the window and.when completed, the screen is firmly held in place and free to be raised to the extent permitted by engagement of the movable lower brackets on the screen with the relatively stationary upper brackets on the sash guides, these serving as cooperating stops preventing accidental or unintentional disengagement of the screen. The screen may be removed at any time by simply unfastening the lower brackets from the screen and then slipping the screen out of the upper brackets. Both sets of brackets, the upper single channels and the lower double reversely facing channels can be short in length, inconspicuous and inexpensive.

I claim:

In combination with a window structure ineluding outer sash guides, a movable half window screen slidingly engaged between said sash guides and slide brackets "for said screen, comprising an upper pair of relatively stationary channel brackets mounted on said sash 'guides with the channels of the same faced inwardly of the window frame and slidingly receiving the upper portion of said screen and a lower pair of relatively movable channel brackets mounted on the lower portion of said sliding screen with the channels of the same faced outwardly and slidingly engaged over said sash guides below said upper relatively stationary brackets. 2. In combination with a window structure ineluding outer sash guides, a movable half window screen slidingly engaged between said sash guides and slide brackets for said screen, comprising an upper pair of relatively stationary channel brackets mounted on 'said sash guides with the channels of the samefaced inwardly of the window frame and slidingly receiving the upper portion of said screen and a lower pair of relatively movable channel brackets mounted on the lower portion of said sliding screen with the channels of the same faced outwardly and slidingly engaged over said sash guides below said upper relatively stationary brackets, said lower brackets having inwardly projecting lugs extending over the screen in position accessible at the inside of the window and readily engageable and releasable fastenings securing said accessibly placed lugs to said screen and whereby said lower brackets can be attached to and removed from the screen after the screen has been engaged in sliding relation in the channels of the stationary upper brackets.

3. In combination with a window structure including outer sash guides, a movable half window screen slidingly engaged between said sash guides and slide brackets for said screen, comprising an upper pair of relatively stationary channel brackets mounted on said sash guides with the channels of the same faced inwardly of the window frame and slidingly receiving the upper portion of said screen and a lower pair of relatively movable channel brackets mounted on the lower portion of said sliding screen with the channels of the same faced outwardly and slidingly engaged over said sash guides below said upper relatively stationary brackets, said lower bracketshavirig inwardly facing channels receiving the lower portion of the screen and defined by flanges engaging over the inner and outer faces of the screen, said flanges at the inside of the window being perforated and fastenings entered through said perforated flanges for securing said lower brackets to said screen.
